The Birimian is composed of a series of sub-parallel linear arcuate north-east-south-west or north-south trending granitoid-greenstone belts (namely the Kibi-Winneba (Kw), Ashanti (As), Bui (Bu ...
The volcano-metasedimentary Bui belt in Ghana is one of the lesser known Birimian belts of the West African Craton that provide constraints on Paleoproterozoic crustal growth. This study presents the first major, trace element and Nd-Hf isotope data for the mafic suite of the Bui belt to constrain their petrogenesis and geodynamic setting.
A multicriterion approach has made it possible to propose a paleoproterozoic evolution of the Ghanaian province and a gold-emplacement model in terms of structural control, geodynamic context ...

The pegmatites at Winneba host very large metric crystals of spodumene, that make up to 20% of the . Conclusions. The Winneba-Mankoadze area offers the opportunity to study highly differentiated, strongly mineralized pegmatites of the LCT family and albite-spodumene type along the coast between Accra and Cape Coast in southern Ghana.
and granitoid-hosted enclaves from the Palaeoproterozoic Lawra Belt of Ghana were analysed for geochemical and Sr–Nd isotopic data to constrain the geological evolution of the southeastern part of the WAC. The metavolcanic rocks display mainly tholeiitic signatures, whereas the enclaves show calc-alkaline signatures. The high SiO
